Clamp type duck bill valve, rubber check valve, duck bill rubber check valve is widely used in coast, beach, wharf, reservoir, municipal flood discharge, sewage, can be described as environmental green valve, the valve replaces the tap door check valve, completely solve the problem that the tap door is easy to be blocked by sediment, silt, stone, vegetation, Marine life. Clamp type duck bill valve products main applications: used in waterproofing system, discharge system, pump outlet, lifting pump station and liquid aeration system.

Product code: duck bill valve, rubber check valve, sewage check valve, check valve;

Domestic models: XH81, XH81A, XH41, XH41A;

Atlas label: duck-bill valve type code shut-off valve letter J, connection form code flange number 4, structural material natural rubber letter NR, duck-bill valve lining material (nitrile rubber, EPDM, silicone rubber, PTFE lining, etc.), nominal pressure PMa.

Flange type duck bill valve uses:

The valve does not have any active components belonging to the flexible rubber check valve, in the sewage drainage system, rainwater drainage system, underground parking lot drainage and other systems, with odor blocking, prevent sewage backflow function, can prevent flooding, sewage backflow into the basement or municipal pipes, and 80% of the duck bill valve material belongs to natural rubber corrosion resistance, Acid and alkali resistance eliminates any daily maintenance, and can be used normally without being affected after several years of idling, thus avoiding property damage caused by media reflux. Widely used: coast, beach, wharf, reservoir, municipal sewage pipe mouth and so on.

Installation method:

1, the valve does not have any moving components, the installation method, technical parameters, technical requirements of the pipe flange through the mouth (pressure or back pressure, temperature, corrosion conditions can be met).

2, check the flange type duck-bill valve inside and outside the thought of damage, check the valve for dirt and so on.

3. Check whether the outer surface of the installation pipe or the connection flange has burrs, deformation, and whether it is smooth and flat. Be careful to avoid collision with hard objects or sharp pipe walls when installing the duckbill valve surface.

4, flange type duck-bill valve installation, the outlet flange size of the drain pipe should be corresponding to the size of the duck-bill valve connection flange, between the flange and the flange depending on the specific situation, install a gasket to ensure the absolute seal after the connection is tightened; It should also be noted that the flange lip of the duck bill valve cannot be damaged.

5, the installation of diameter greater than DN800 duck mouth hair, due to the large weight of the valve body, coupled with the work, the valve body cavity has a lot of water and water impact, it is necessary to add a supporting rod, through the valve body on the ring, the valve body long-term stable lifting.

Note:

1, the valve body in the handling, storage, installation, to avoid non-standard operation.

2, if the valve body is stored for a long time, to prevent open flame. Stacking is strictly prohibited.

3, in normal use, no maintenance is required, but to prevent sharp objects from poking through the duck bill valve.

4, the working part can not have the extrusion of the object, so as not to affect its natural opening and closing.

Instructions for ordering:

1. The user shall provide the description and technical requirements of the working conditions on site.

2, the user should provide the necessary technical parameters, including the nominal diameter of the pipeline, the outside diameter of the pipeline interface, the installation type and the value of the positive opening pressure and the reverse reverse backpressure. Our technical staff will be based on the requirements of users, for the user selection design.

Product Features

1. High-quality materials: The valve is made of EPDM rubber, which is resistant to corrosion, aging, and high temperatures.

2. Flanged connection: The valve is designed with a flanged connection, which makes it easy to install and replace.

3. Anti-backflow design: The duckbill-shaped valve body can effectively prevent the backflow of sewage, ensuring the smooth flow of the pipeline.

4. Long service life: The valve has a long service life and can be used for a long time without maintenance.

5. Easy maintenance: The valve is easy to maintain and clean, and can be replaced quickly in case of damage.

Product Applications

This duckbill check valve is widely used in sewage treatment plants, municipal drainage systems, and industrial wastewater treatment systems. It can be installed in pipelines to prevent the backflow of sewage and ensure the smooth flow of the pipeline.
